摘要
文章对9个不同类型牧草品种在呼和浩特地区的生育特性进行了观测,结果表明,苜蓿在4月底之前播种时,播种后10～14d 出齐苗,6月底现蕾,7月中下旬开花,8月末到9月初期种子成熟。同期播种,禾本科牧草比苜蓿的生长速度慢。牧草刈割后的再生速度与牧草种类和品种有关。苜蓿刈割后的再生速度快于禾本科牧草。在4个苜蓿品种中,以 FGC301和 FGC201再生速度较快;4个禾本科牧草中,鸭茅再生速度最快。在9个供试牧草品种中,肇东苜蓿、多年生黑麦草和苇状羊茅因抗病性差、越冬率低,不适合在呼和浩特地区种植。紫花苜蓿FGC-301、FGC-201及无芒雀麦适合在呼和浩特地区推广种植。
The growth characters of different forage grasses and alfalfa varieties were studied in this trial. The results indicated the growth sequences of alfalfa were sowing in the end of April,emergence 10-14 days after sowing,squaring in the end of June,flowering in 20 July and maturing in the end of August or in the beginning of September.Forage grasses grow slowly than alfalfa in the same sowing date with alfalfa.The reproduction rate varied in different cuhivars and the reproduction rate of alfalfa were faster than forage grasses.The reproduction rate of FGC-301 and FGC-201 were faster among 4 alfalfa cultivars,the reproduction rate of orchard grass was fastest among 4 forage grasses.Zhaodong alfaifa,perennial rye-grass and reed fescue had weak disease-resistance and lower surviving rates among 9 cuhivars.In general,FGC-301 and FGC-201 in alfalfa varieties and awnless brome were adapted in Hohhot.
